I Had a bunch of Roos a while back, and they did alot of damage to my girls back feathers and shoulders, all is growing back since I culled most of them(roos). However I have 2 Cochin girls that look like they have had the scull caps ripped loose , One kinda hangs to the side alittle and is very hard, the other is upright but swollen and hard, both of the girls are eating and moving about fine and don't act as if there is any brain damage, but you can physically move the swollen part around with your fingers like you would a knee cap. The swelling does not seem to be going down , Is there anything I can do to help them? Thankyou for your help! Sandy
